is y= l x^2 - 16 l at x=4 a Corner? vertical tangent? Discontinuity? or Differentiable?
If you graph it using a graphing calc, you will find the answers to all your questions.
How do you graph it on the calculator?
What kind of calculator do you have?
a TI-84 silver edition, graphing calculator
Thank you !
For your calc, if I'm not mistaken it should be: abs(x^2 - 16)
It is, but the window is zoomed in too much, so I cant hardly distinguish anything
i can hardly **
Well, zoom it out. Use window: -10 < x < 10 0 < y < 100
